[Java] More Differences Between Sword Tiers

Swords of different tiers should have different abilities, to make the process of upgrading to a new sword more rewarding. The stats below may not be perfectly balanced, but should at least serve to show what I mean. 

Wood:

• Cannot perform a Sweep Attack.
• Cannot perform Critical Hits.

Stone: 

• Cannot perform a Sweep Attack.
• Can perform Critical Hits

Iron:

• Can perform a Sweep Attack.
• Can perform Critical Hits
• Sweep Attack does 1.6 block knockback

Gold: 

• Can perform Sweeps and Critical Hits
• Still does 4 damage
• 1.2 Attack Speed
• Sweep Attack does 1.2 block knockback
• even worse durability to compensate

Diamond

• Can perform Sweeps and Critical Hits
• Sweep Attack does 2.3 block knockback

Netherite

• Can perform Sweeps and Critical Hits
• Sweep Attack does 2.8 block knockback
• Enchantments are 1.2x more effective. 

By making lower tier swords weaker and higher tier swords stronger, the process of upgrading to a better sword will feel more satisfying. It would also further incentivize upgrading in the first place.
